From 762778861507f2795f6e1c15856eab4f960aaf64 Mon Sep 17 00:00:00 2001 From: Stan Grishin Date: Mon, 18 Mar 2024 01:43:50 +0000 Subject: [PATCH] pbr: update to 1.1.4-5 This update includes the following changes: 1. Makefile * update copyright * attempt to implement the proper variants to avoid luci-app dependency on both variants * quietly stop service on uninstall 2. Config-file * add the list of dnsmasq instances to target in supported dnsmasq modes * for default pbr variant, set the `resolver_set` to `dnsmasq.nftset` * for iptables pbr variant, set the `resolver_set` to `dnsmasq.ipset` * add the `nft_file_support` (disabled by default) * introduce `procd_boot_delay` to delay service start on boot * introduce the following nft set creation options: * nft_set_auto_merge * nft_set_counter * nft_set_flags_interval * nft_set_flags_timeout * nft_set_gc_interval * nft_set_policy * nft_set_timeout * add the pbr.user.wg_server_and_client custom user script to allow running wg server and client at the same time * add the "Ignore Local Requests" sample policy 3. Hotplug firewall/interface scripts * better logged messages 4. The pbr and pbr-iptables uci defaults script * use functions from the init script * improve vpn-policy-routing migration 5. The pbr-netifd uci defaults script * use functions from the init script * improve uci operations 6. Introduce the firewall.include file 7. Improve pbr.user.aws custom user script 8. Improve pbr.user.netflix custom user script 9. Introduce pbr.user.wg_server_and_client custom user script 10. Update the init file: * refactor some code to allow the init script file to be sourced by the uci defaults scripts and the luci rpcd script for shared functions * add support for `nft_file_mode` in which service prepares the fw4-compatible atomic nft/include file for faster operations on service reload * improve Tor support (nft mode only) * implement support for nft set options * update validation functions for new options/parameters Signed-off-by: Stan Grishin (cherry picked from commit 790753f6a65c1805e6de817fba009aa8fc6402dc) --- net/pbr/Makefile | 73 +- net/pbr/files/etc/config/pbr | 27 +- net/pbr/files/etc/config/pbr.iptables | 7 +- net/pbr/files/etc/hotplug.d/firewall/70-pbr | 2 +- net/pbr/files/etc/hotplug.d/iface/70-pbr | 4 +- net/pbr/files/etc/init.d/pbr | 2910 +++++++++++++++++ net/pbr/files/etc/uci-defaults/90-pbr | 41 +- net/pbr/files/etc/uci-defaults/91-pbr | 31 +- net/pbr/files/usr/share/pbr/.keep | 0 net/pbr/files/usr/share/pbr/firewall.include | 5 + net/pbr/files/usr/share/pbr/pbr.user.aws | 49 +- net/pbr/files/usr/share/pbr/pbr.user.netflix | 64 +- .../share/pbr/pbr.user.wg_server_and_client | 22 + net/pbr/test.sh | 2 +- 14 files changed, 3129 insertions(+), 108 deletions(-) create mode 100755 net/pbr/files/etc/init.d/pbr create mode 100644 net/pbr/files/usr/share/pbr/.keep create mode 100644 net/pbr/files/usr/share/pbr/firewall.include create mode 100644 net/pbr/files/usr/share/pbr/pbr.user.wg_server_and_client diff --git a/net/pbr/Makefile b/net/pbr/Makefile index 744db6ab67..d5a9503ed4 100644 --- a/net/pbr/Makefile +++ b/net/pbr/Makefile @@ -1,73 +1,80 @@ -# Copyright 2017-2022 Stan Grishin (stangri@melmac.ca) +# Copyright 2017-2023 MOSSDeF, Stan Grishin (stangri@melmac.ca) # This is free software, licensed under the GNU General Public License v3. include $(TOPDIR)/rules.mk PKG_NAME:=pbr -PKG_VERSION:=1.1.1 -PKG_RELEASE:=7 +PKG_VERSION:=1.1.4 +PKG_RELEASE:=5 PKG_LICENSE:=GPL-3.0-or-later PKG_MAINTAINER:=Stan Grishin include $(INCLUDE_DIR)/package.mk -define Package/pbr/Default +define Package/pbr-service/Default SECTION:=net CATEGORY:=Network SUBMENU:=Routing and Redirection TITLE:=Policy Based Routing Service URL:=https://docs.openwrt.melmac.net/pbr/ DEPENDS:=+ip-full +jshn +jsonfilter +resolveip + DEPENDS+=+!BUSYBOX_DEFAULT_AWK:gawk + DEPENDS+=+!BUSYBOX_DEFAULT_GREP:grep + DEPENDS+=+!BUSYBOX_DEFAULT_SED:sed + PROVIDES:=pbr-service CONFLICTS:=vpnbypass vpn-policy-routing PKGARCH:=all endef define Package/pbr -$(call Package/pbr/Default) +$(call Package/pbr-service/Default) TITLE+= with nft/nft set support DEPENDS+=+kmod-nft-core +kmod-nft-nat +nftables-json - VARIANT:=nftables - PROVIDES:=vpnbypass vpn-policy-routing DEFAULT_VARIANT:=1 + VARIANT:=nftables + PROVIDES+=pbr vpnbypass vpn-policy-routing endef define Package/pbr-iptables -$(call Package/pbr/Default) +$(call Package/pbr-service/Default) TITLE+= with iptables/ipset support DEPENDS+=+ipset +iptables +kmod-ipt-ipset +iptables-mod-ipopt VARIANT:=iptables - PROVIDES:=pbr endef define Package/pbr-netifd -$(call Package/pbr/Default) +$(call Package/pbr-service/Default) TITLE+= with netifd support VARIANT:=netifd - PROVIDES:=pbr +endef + +define Package/pbr-service/description + This service enables policy-based routing for WAN interfaces and various VPN tunnels. endef define Package/pbr/description -This service enables policy-based routing for WAN interfaces and various VPN tunnels. -This version supports OpenWrt with both firewall3/ipset/iptables and firewall4/nft. + $(call Package/pbr-service/description) + This version supports OpenWrt with both firewall3/ipset/iptables and firewall4/nft. endef define Package/pbr-iptables/description -This service enables policy-based routing for WAN interfaces and various VPN tunnels. -This version supports OpenWrt with firewall3/ipset/iptables. + $(call Package/pbr-service/description) + This version supports OpenWrt with firewall3/ipset/iptables. endef define Package/pbr-netifd/description -This service enables policy-based routing for WAN interfaces and various VPN tunnels. -This version supports OpenWrt with both firewall3/ipset/iptables and firewall4/nft. -This version uses OpenWrt native netifd/tables to set up interfaces.
